CARACAS, Aug 9 (Reuters) - A United States court has approved a request by Canadian gold miner Crystallex to attach shares in a U.S. subsidiary of Venezuelan state oil company PDVSA that indirectly controls refiner Citgo, according to a filing on Thursday.
Crystallex is seeking to collect a $1.4 billion award in compensation following a decade-long dispute over Venezuela's 2008 nationalization of Crystallex gold mining operation in the South American nation.
Judge Leonard P. Stark of the United States District Court in Delaware granted Crystallexs request but held off actually issuing a writ to attach seizure order until the parties advised him on how to proceed. The judge also let the parties propose a redacted ruling before he issues a public decision.
PDVSA and a lawyer representing Crystallex did not immediately respond to a request for comment. A source close to PDVSA said the Caracas-based company was mulling an appeal.
The cash-strapped Venezuelan government has little in the way of offshore assets which has encouraged creditors to consider ways to pursue Citgo, a PDVSA subsidiary.
Houston-based Citgo was valued as high as $10 billion during an aborted 2014 sale process.
Venezuelas opposition said leftist President Nicolas Maduro was putting the OPEC nations assets at risk.
Were starting to lose foreign assets because of this irresponsible and corrupt government, said opposition lawmaker Angel Alvarado.
